Why Irish Stout tastes like it does

These structural drivers explain its characteristic flavour balance.

  • Very high roast level creates very dark colour, intense roast flavour, firm bitterness and a pronounced roasted character dominating the malt profile.
  • Roasted barley produces intense dry roast and stout-like character.
  • Pale ale malt provides a clean, lightly biscuity base with moderate body and a gentle malt backbone.
  • Classic English ale yeast with balanced fruity esters and a gentle, malt-forward profile.
  • Moderately hard water sharpens hop brightness and increases minerality while slightly reducing fullness.
